Verify Network Connectivity with Ping

You can use the Ping program to verify network connectivity to NNTP Service. You can verify whether the Domain Name System (DNS) is correctly resolving the computer name to the IP address.

Because problems can occur at many places in the network, it is preferable to verify connectivity from the client that cannot connect to Microsoft NNTP Service; however, if necessary, you can verify connectivity from any computer on the network.

To verify network connectivity:

  1. On the Start menu, point to Programs, click Accessories, and then click Command Prompt.
  2. At the command prompt, type the following command:

    ping server_name

    Server_name is the DNS name of the computer on which NNTP Service is running.

  3. Your results will match one of the following scenarios.

    Reply from 
    bytes=32 time<10ms TTL=128

    bytes=32 time<10ms TTL=128
    You can contact the server by its DNS name. To verify that the IP address resolves correctly, at the command prompt, type the IP address returned in the response.

    ping IP_address

    Bad IP address

    If you do not get a successful response by IP address, a network connectivity problem exists. Work with your network administrator to identify and correct the network problem.

Tip   For help with Ping command syntax, type ping -? at the command prompt.

If the response from the Ping command shows a time value greater than 10 milliseconds, ask your network administrator to check for network congestion problems.
